Hi guys,
I'm using dialectic + Bria 3 as a softphone/dialing combo which gives me full power - AppleScripting, tel:// URLs etc.
Because I couldn't find an existing Alfred2 workflow for Bria/dialectic, I just created one. You can download the workflow on the github repo. Remember to configure Contact action custom field "Phone" pointing to this workflow - now you can select any contact from your address book and dial its number.
As a requirement, you need dialectic (http://www.jonn8.com/dialectic/) installed!

Have fun!
